Abstract:We investigate which invariants of groups are powerful in distinguishing non-isomorphic p-groups. Based on this, we devise an effective algorithm to solve the group identification problem for the $10,494,213$ groups of order $2^9$. We exhibit a list of groups of order $2^9$ which are difficult to distinguish y invariants and thus are the most difficult cases for our algorithm.
